Description

Technical Field

[0001] This utility model relates to the field of oxygen and acetylene cylinder transfer technology, and in particular to a special vehicle for oxygen and acetylene cylinders. Background Technology

[0002] Metal cutting and welding are required for equipment maintenance and installation in mines. Oxygen cylinders and acetylene cylinders are essential equipment in metal cutting and welding, and the technology has been used for many years. Oxygen cylinders and acetylene cylinders often need to be moved during use to facilitate nearby operations.

[0003] A hand-pushed transport vehicle for oxygen and acetylene cylinders (Announcement No.: CN 205916155 U) includes a frame (1) and two wheels (2). The frame (1) includes a support base plate (11), two longitudinal beams (12), and outriggers (13). The body of the support base plate (11) is perpendicular to the long axis of the two longitudinal beams (12). One long side of the support base plate (11) is laterally connected to the end of the two longitudinal beams (12) in the same direction. The two wheels (2) are rotatably mounted on the two longitudinal beams (12). The outriggers (13) are laterally connected to the other end of the two longitudinal beams (12). A U-shaped oxygen and acetylene cylinder fixing plate (3) with a concave cross-section facing the wheel (2) is installed between the two longitudinal beams (12). It can be conveniently used to transport oxygen and acetylene cylinders, preventing surface wear and deformation during transportation and improving their service life. It can also be used as a support for oxygen and acetylene cylinders.

[0004] While the aforementioned technology facilitates the transfer of oxygen or acetylene cylinders, it makes it difficult to secure the transport vehicle after transfer, resulting in poor stability of the oxygen or acetylene cylinders. Therefore, there is room for improvement. Utility Model Content

[0005] This utility model provides a special vehicle for oxygen and acetylene cylinders to solve the problems mentioned in the background art.

[0006] To address the aforementioned issues, this utility model provides a special vehicle for oxygen and acetylene cylinders, comprising a frame, wheels, a support plate, and an auxiliary frame. The frame has a handrail at its upper end and two wheels symmetrically mounted at its lower end. The support plate is mounted at the bottom of the frame, above the two wheels. The tops of both sides of the auxiliary frame are rotatably connected to the upper sides of the frame. Two auxiliary wheels are symmetrically mounted at the bottom of the auxiliary frame. A connecting seat is mounted on each side of the lower end of the auxiliary frame, and a support rod is rotatably connected to each connecting seat. A positioning post is fixedly mounted on the lower outer side of the frame. A groove is provided at the end of the support rod away from the auxiliary frame, allowing it to slide against the positioning post. A threaded hole is provided in the positioning post. U-shaped sleeves covering the positioning post are provided at both ends of the groove in the support rod. An arc-shaped protective plate is provided on the front side of the frame. One side of the arc-shaped protective plate is hinged to the frame, and the other side has a first positioning cylinder. A second positioning cylinder corresponding to the first positioning cylinder is provided on one side of the frame. A pin is provided in the frame to insert the first and second positioning cylinders.

[0007] Preferably, the wheel at the bottom of the support plate is equipped with a foot brake.

[0008] Preferably, a semi-circular positioning plate is installed on the rear side of the support plate, and a rubber buffer pad is installed on the inner wall of the positioning plate.

[0009] Preferably, a positioning bolt that is threadedly connected to a threaded hole is movably installed in the U-shaped sleeve.

[0010] Preferably, a rubber cushioning pad is installed on the top rear side of the frame.

[0011] Preferably, the top and bottom parts of the inner wall of the arc-shaped protective plate are respectively equipped with rubber buffer pads.

[0012] The beneficial effects of adopting the above technical solutions are:

[0013] 1. The oxygen cylinder and acetylene cylinder can be stably fixed in the frame by the support plate, positioning plate and arc-shaped protective plate. The rubber buffer pad prevents the surface of the oxygen cylinder and acetylene cylinder from directly contacting the frame, arc-shaped protective plate and positioning plate during movement, thus avoiding wear on the cylinder body.

[0014] 2. The auxiliary frame makes oxygen cylinders and acetylene cylinders more stable during transport and placement during operation, reducing the risk of tipping over and improving safety.

[0015] 3. The top of the auxiliary frame is rotatably connected to the top of the vehicle frame. With the addition of support rods and positioning columns, the auxiliary frame can be folded and stored, which makes it easier to reduce the footprint of the special vehicle when it is not in use and facilitates storage.

[0023] like Figure 1-3In this embodiment, a special vehicle for oxygen and acetylene cylinders includes a frame 1, wheels 2, a support plate 3, and an auxiliary frame 4. The frame 1 has a handrail 11 at its upper end and two wheels 2 symmetrically mounted at its lower end. The support plate 3 is mounted at the bottom of the frame 1 and located above the two wheels 2. The top two sides of the auxiliary frame 4 are rotatably connected to the upper sides of the frame 1. Two auxiliary wheels 41 are symmetrically mounted at the bottom of the auxiliary frame 4. A connecting seat 42 is mounted on each side of the lower end of the auxiliary frame 4, and a support rod 43 is rotatably connected to each connecting seat 42. A certain amount of material is fixed to the lower outer side of the frame 1. Positioning post 12, the support rod 43 has a groove 44 at one end away from the auxiliary frame 4 that is slidably connected to the positioning post 12, the positioning post 12 has a threaded hole, the two ends of the groove 44 in the support rod 43 are respectively provided with U-shaped sleeve plates 45 covering the positioning post 12, the front side of the frame 1 is provided with an arc-shaped protective plate 5, one side of the arc-shaped protective plate 5 is hinged to the frame 1, and the other side is provided with a first positioning cylinder 51, one side of the frame 1 is provided with a second positioning cylinder 13 corresponding to the first positioning cylinder 51, and the frame 1 is provided with a pin 14 that passes through the first positioning cylinder 51 and the second positioning cylinder 13.

[0024] With the above technical solution, when transporting oxygen cylinders and acetylene cylinders, the cylinder is first placed on the support plate 3 of the frame 1.

[0029] Preferably, a positioning bolt 451 that is threadedly connected to a threaded hole is movably installed in the U-shaped sleeve plate 45.

[0030] Through the above technical solution, the threaded connection between the positioning bolt 451 and the threaded hole in the positioning column 12 can ensure a stable connection between the U-shaped sleeve 45 and the positioning column 12, thereby ensuring the stability of the auxiliary frame 4 in both its unfolded and retracted states.

[0031] Preferably, a rubber buffer pad 6 is installed inside the rear frame of the vehicle frame 1.
